allows for either the humidifier head or the vaporizer head to be securely
fastened to the bucket member.
2. Description of the Related Art
2o The use of vaporizers and humidifiers are well known. Examples
of a vaporizer and a humidifier are disclosed in U.S. Patent No. 5,693,270
and U.S. Patent No. 5,607,627, respectively. Vaporizers are commonly
used when one desires to introduce moisture in the form of steam into the
atmosphere to break-up congestion in the user's lungs or nasal passages.
2s Also, medication is sometimes placed on the vaporizer head so that the
medication can be transported by the steam to the user's respiratory
system. Humidifiers are commonly used when one desires to introduce
moisture in the form of a cool mist into the atmosphere to eliminate dry
air soothing a sore throat or cough. In general, humidifiers are used when
3o it is desired to only counteract dryness in the air. Whereas, vaporizers,
CA 02256775 1999-O1-08
although also used to add moisture to the atmosphere and counteract
dryness in the air, are used to break-up congestion in the user's lungs or
nasal passages. Because humidifiers and vaporizers are used for different
purposes, a household may need to purchase both a humidifier and a
5 vaporizer.
Nowhere in the related art is there disclosed or suggested a device
which has the capacity to function as a humidifier and as a vaporizer.
Therefore, there is a definite need for the present invention which
performs the functions of both a humidifier and a vaporizer and
to eliminates the need and expense of purchasing both a vaporizer and a
humidifier.
SUMMARY OF THE INVENTION

1 o atmosphere, specifically, a combination humidifier/vaporizer.
Figure 1 illustrates the humidifier configuration of the combination
vaporizer/humidifier 10 of the present preferred invention substantially
comprising a bucket member 12, and a humidifier head 14. This
configuration is employed when the user desires for the combination
vaporizer/humidifier 10 to function as a humidifier and release a cool
mist into the environment. The humidifier head 14 preferably is of the
type disclosed in U.S. Patent No. 5,607,627 but other types of humidifier
heads can be used. The humidifier head 14 preferably has a vented top
housing 17, a fan (not shown) for producing the flow of air in the top
2o vented housing 17, a motor (not shown) also positioned within the top
vented housing 17 and an impeller assembly 19.
The bucket member 12 defines a reservoir 16 and an opening 18.
A more detailed description of the bucket member 12 will follow when
describing Figure 2. The edge 20 of the opening 18 forms a cross-section
that is sized and proportioned such that the impeller assembly portion 19
of the humidifier head 14 is received therein and the humidifier head 14
is securely connected to the bucket member 12 by a snap fit method
wherein two rear U-shaped finger members 41 (one of which is not
shown) are provided on the top vented housing 17 which engage
4
CA 02256775 1999-O1-08
apertures 42 of the bucket member 12 such that the humidifier head 14 is
pivoted about the finger members 41 to a horizontal upright position.
Referring to Figure 2, the combination vaporizer/humidifier 10 is
shown employing the vaporizer head 24 which provides for the release of
s steam into the environment. The vaporizer configuration of the
combination vaporizer/humidifier 10 has the bucket member 12 as shown
in Figure l, a vaporizer head 24, and an adapter plate 26. The adapter
plate 26 functions to securely attach the vaporizer head 24 to the bucket
member 12 wherein the vaporizer head 24 is not sized and proportioned
t o to be directly securely attached to the bucket member 12.
The adapter plate 26 has a planar surface 28 defining an opening 30
through which the vaporizer head 24 extends and side members 32. The
planar surface 28 further defines key ways 39. First connectors 34 are
positioned on one side member 32 of the adapter plate 26 and second
is connectors 36 are positioned on an opposing side member 32 of the
adapter plate 26. Although not shown, there are two second connectors
36 positioned along the side member 32. The first connectors 34 are
preferably tab members 38 and the second connectors 36 are preferably
spring fingers 40 which have a U-shaped configuration.
2o The vaporizer head 24 preferably has a cover member 25 and a
heating unit assembly 27 wherein the heating unit assembly 27 has a pair
of electrodes (not shown) positioned within a housing 29 and the cover
member 25 has a hole 31 throughwhich vapors can be emitted from the
vaporizer into the environment. The vaporizer head 24 also has two tab
25 members 33 (one of which is not shown) extending therefrom. The tab
members 33 are positioned diametrically opposite of one another on the
housing 29. Preferably, the vaporizer will perform substantially as
described in U.S. Patent No. 5,693,270. However, although not
CA 02256775 1999-O1-08
illustrated, the vaporizer head can take a variety of forms and include a
variety of features.
The bucket member 12 has apertures 42 which receive the first and
second connectors 34 and 36 and which are positioned along opposite
s ends of the bucket member 12. Although the first and second connectors
34 and 36, as illustrated, are the preferred configurations, various other
types of connectors can be used.
In order to assemble the combination vaporizer/humidifier 10
having the vaporizer head 24, the adapter plate 26 securely attaches to the
1 o bucket member 12 by first placing the tab members 3 8 into the apertures
42 and then pivoting the adapter plate 26 such that the spring fingers 40
engage the apertures 42 positioned at the other end of the bucket member -
12. Once the adapter plate 26 is in position and the opening 30 of the
adapter plate 26 and the opening 18 of the bucket member 12 are

24 is inserted through the adapter plate opening 30 and the bucket
member opening 18 such that it extends into the reservoir of the bucket
member 12. When inserting the vaporizer head 24 within the bucket
member 12, the tab members 33 (one of which is not shown) are aligned
2o with the key ways 39 and then the vaporizer head 24 is rotated to lock it
in position forming a bayonet connection and preventing the vaporizer
head 24 from being directly pulled out of the bucket member 12.
Although not illustrated, other types of connections can be used in place
of the tab members 33 and key way 39 connection.
2s Although not disclosed, the adapter plate can be sized and
proportioned to be used with the humidifier head when the humidifier
head is not configured to be securely attached to the bucket member. In
other words, in the instance where the vaporizer head and bucket member
are configured to be securely attached to one another without the use of
6
CA 02256775 1999-O1-08
an adapter plate, an adapter plate can be used to allow for the humidifier
head to be securely attached to the bucket member and eliminate the need
for a second bucket member.
